I have 8 roosters in a bachelor pen. They are all between 6-8 months old. They have been in the bachelor pen for about two weeks. 3 of them have decided to gang up on the one. I found him a few days ago with his comb torn and covered in blood. I separated him for a bit to recover. Once I put him back in the others they trapped him in a corner and were attempting to mate with him. This is happening pretty consistently. Will the 3 roosters become less aggressive toward the other one? Is there something I can do to get them to integrate better? or do I need to rehome the 3 aggressive/dominant ones?
